Baron--
Sharing personal experiences is always a good idea and it adds a great deal of 'personal touch'. The tips are also a good idea.
Have you considered having recent alumni or 'soon-to-graduate' students come in and share as well? Sometimes it is highly effective to have students speak with students...they relate. If you can't get students/alumni in person, taping them and showing the video could also work. Obviously, live is best.
